Free Online URL Encode and Decode Tool

Percent-encode URLs and query strings, or decode them back to readable text — instantly and privately.

Hey there! Special characters like spaces, question marks, ampersands, and accents can break URLs. Our free URL Encode / Decode tool helps you safely convert them using percent-encoding. Whether you are building API requests, handling query parameters, or cleaning up links, this tool makes it quick and simple.

Everything runs in your browser — 100% private, no signup, and no data is sent anywhere.

What is URL Encoding?

URL encoding (also known as percent-encoding) replaces special characters with a % followed by their hexadecimal code. For example, a space becomes `%20` and an ampersand `&` becomes `%26`. This ensures URLs remain valid when they contain spaces or reserved characters.

encodeURIComponent vs encodeURI – Which One to Use?

  • encodeURIComponent – Encodes almost every special character. Best for query parameter values (like search terms or usernames).
  • encodeURI – Keeps URL structure characters like : / ? # & = intact. Best for encoding a complete URL.

When Should You Use This Tool?

  • Building URLs with query parameters that contain spaces or special characters
  • Encoding user input before sending it in API requests
  • Decoding URLs received from browsers or external sources
  • Fixing broken links that contain encoded characters
  • Working with redirects or deep links in web applications
